PROBLEM TO BE SOLVED: To provide a pneumatic tire having secured land part rigidity and improved heat radiation effect on a tread part.SOLUTION: A striation 9 extending in an inclined direction with respect to a tire circumferential direction on a tread surface 1 and having groove width W1 smaller than a groove depth D1 is formed. Both ends of the striation 9 open to outside of a land part, and on at least one of groove wall faces 9c of the striation 9 with respect to the tire circumferential direction, an air inflow part 10 opening to the tread surface is formed. The maximum depth D1 of the striation 9 and the maximum depth D2 of the air inflow part 10 satisfy 5<D1/D2≤15. |
